My doctor prescribed me phentermine 37.5 to lose weight since I'm obese. I'm having a hard time starting it because I'm very medication resistance. I'm scared of the side effects. I have OCD and Anxiety and I'm worried it will make it worse. I really want to take this drug because I know I need it. I'm very unhealthy due to my weight. Anyone have any feedback on side effects or tips to avoid them?
